Therefore, the embodiment of the present invention proposes a kind of DPCCH transmission method, reference picture 1, transmitting terminal（UE sides）DPCCH transmission method comprise the following steps：
Step 11, UE generates the first TPC information and the 2nd TPC information, wherein described first TPC information is used for the downlink power control for indicating the base station belonging to first community, and the 2nd TPC information is used for the downlink power control for indicating the base station belonging to second community.
Step 12, the base station belonging to UE to the first community sends the first TPC information, and the base station belonging to the second community sends the 2nd TPC information.
More than, first community provides service with second community.
As can be seen here, due to two TPC information of generation, and the two TPC information indicate respectively the downlink power control of the base station belonging to two different districts, it is meant that two downlinks carry out independent power control operation.It may therefore be assured that when two downlink quality differences are blunt big, the individual power control of this two downlinks ensure that the power control performance of both links respectively.
In one embodiment, UE can be by changing the time slot formats of up DPCCH channels, the first TPC information and the 2nd TPC information or the first TPC information and the 2nd TPC information that generate combined coding of such as generation absolute coding, then as the base station belonging to DPCCH channels ^ carries the first TPC information and the 2nd TPC information is sent to first community and the base station belonging to second community.
Table 1 below and table 2 sets forth the example of absolute coding and the DPCCH channel time slot formats of the TPC information of combined coding the first and the 2nd TPC information.
Wherein, table 1 is to add time slot format on the basis of existing DPCCH time slot formats（ slot format ) 5 , NTPC1And NTPC2The first TPC information and the 2nd TPC information are represented respectively.Two TPC command words of carrying occupy 2 bits respectively, it is possible to achieve two independent downlink power controls. Table 1:DPCCH time slot formats
Wherein, table 2 is to add time slot format on the basis of existing DPCCH time slot formats（Slot format) 6, wherein, the first TPC information and the 2nd TPC information carry out combined coding, and 3 bit, NTPCI＆NT are occupied altogetherPC2Represent the first TPC information and the 2nd TPC information of combined coding.Two independent downlink power controls can also be realized.Table 2:DPCCH time slot formats
It should be understood that Tables 1 and 2 depicted herein is only illustrative, it is not restricted.True first TPC information and the 2nd TPC information can also use others DPCCH time slot formats.It can be seen that, when the first TPC information and the 2nd TPC information are coded independently, UE can be on identical time slot, and the base station belonging to first community sends the first TPC information respectively, and the base station belonging to second community sends the 2nd TPC information.Then, the base station belonging to first community and the base station belonging to second community can receive the first TPC information and the 2nd TPC information respectively in the different periods in identical time slot.And the base station belonging to first community can receive the first TPC information in the specified location in same time slot, the base station belonging to second community can also receive the 2nd TPC information in the specified location in same time slot.It is set in advance that base station belonging to two cells specifically receives the TPC information of oneself in which position of same time slot.
Or, when the first TPC information and the 2nd TPC information are jointly encoded, UE can be on identical time slot, while sending the first TPC information and the 2nd TPC information of combined coding to the base station belonging to first community and the base station belonging to second community.Then, the base station belonging to first community and the base station belonging to second community can be decoded to the first TPC information of combined coding and the 2nd TPC information respectively, to obtain the TPC information of oneself.For example, as shown in table 2, first TPC information of combined coding and the 2nd TPC information have 3 bits, the TPC information of 2 bits is respectively obtained after base station decoding belonging to base station and second community belonging to first community, as shown in Figure 2, then the base station belonging to first community can determine that the 1st bit is the TPC information of oneself, and the base station belonging to second community can determine that the 2nd bit is the TPC information of oneself.Vice versa, i.e., the base station belonging to first community can also be true Fixed 2nd bit is the TPC information of oneself, and the base station belonging to second community can also determine that the 1st bit is the TPC information of oneself.The TPC information which bit represents the base station belonging to which cell in the bit information of decoding is set in advance.
In another embodiment, UE can also send the first TPC information and the 2nd TPC information respectively using time division way on DPCCH channels, and independent downlink power control is carried out after receiving respective TPC information so as to the base station belonging to two cells.
It is, the first TPC information and the 2nd TPC information are transmitted in a time division manner, wherein the first TPC information and the 2nd TPC information by when Coded.Therefore, when the first TPC information and the 2nd TPC information by when Coded when, is on interval slots, and the base stations of UE respectively belonging to first community send the first TPC information, and the base station belonging to second community sends the 2nd TPC information.Reference picture 3, UE compartment of terrains on continuous time slot send the first TPC information and the 2nd TPC information, base station for example on the time slot of odd number belonging to first community sends the first TPC information, base station on the time slot of even number belonging to second community sends the 2nd TPC information, or the base station on the time slot of even number belonging to first community sends the first TPC information, the base station on the time slot of odd number belonging to second community sends the 2nd TPC information.Because the base station belonging to two cells receives the TPC information of oneself on different time slots, therefore, it is possible to correctly decode the TPC information of oneself, so as to effectively carry out downlink power control.
It should be understood that Fig. 3 example is only illustrative, it is not restricted.In fact, UE can send the first TPC information to the base station belonging to first community respectively on continuous interval slots as shown in Figure 3 and the base station belonging to second community sends the 2nd TPC information.UE can also be respectively separated n time slot and send the first TPC information and the 2nd TPC information of base station transmission belonging to second community to the base station belonging to first community, or, the first TPC information and the 2nd TPC information can be sent with unequal interval.Here n may be greater than or the positive integer equal to 1.Generally, n value is bigger, i.e. the transmission interval of the first TPC information and the 2nd TPC information is bigger, and the performance impact to system is bigger.
As can be seen here, due to two TPC information of generation, and the two TPC information indicate respectively the descending probability control of the base station belonging to two different districts, therefore can independently ensure the down control channel quality of two cells.More than, the statement description merely for convenience of " first " and " second ".It should be readily apparent to one skilled in the art that the statement of " first " and " second " is not referred to particularly, merely to two different main bodys of difference.
Below, reference picture 4 is described, it is proposed that receiving terminal（Base station side）DPCCH method of reseptance.Due in above content to corresponding to transmitting terminal（UE sides）DPCCH transmission method has carried out some descriptions, therefore the content repeated will not be described in great detail.Receiving terminal（Base station side）DPCCH method of reseptance Comprise the following steps：
Step 41, the base station belonging to first community obtains the first TPC information from UE, wherein the first TPC information is used for the downlink power control for indicating the base station belonging to the first community.
Here, first community provides service with second community for UE, and the descending power of the base station belonging to second community is controlled according to the 2nd TPC information.
For example, specified moment of the base station belonging to first community on each time slot receives the first TPC information from UE side joints；Then, the base station belonging to first community decodes the first TPC information, to obtain the first TPC information.Wherein, the specified moment is set in advance.
Or, for example, the base station belonging to first community receives the first TPC information and the 2nd TPC information of combined coding on each time slot from UE, wherein the 2nd TPC information is used for the downlink power control for indicating the base station belonging to second community；Then, the base station belonging to first community decodes the first TPC information and the 2nd TPC information of the combined coding, to obtain the first TPC information in designated bit position.Wherein, designated bit position is set in advance.
Or, for example, the first TPC information is received in base station belonging to first community on assigned timeslot from UE side joints respectively, wherein the first TPC information is transmitted from the 2nd TPC information on different time slots, the 2nd TPC information is used for the downlink power control for indicating the base station belonging to second community；Then, the base station belonging to first community decodes the first TPC information, to obtain the first TPC information.Wherein, assigned timeslot is set in advance.
Step 42, the base station belonging to first community carries out downlink power control according to the first TPC information.As can be seen here, due to two TPC information of generation, and the two TPC information indicate respectively the downlink power control of the base station belonging to two cells, therefore can preferably ensure the down control channel quality of two cells.It is readily appreciated that, is described although Fig. 4 description is angle from the base station belonging to first community, the DPCCH method of reseptances of the base station belonging to second community is also as the base station belonging to first community.
Another receiving terminal that Fig. 5 is shown（Base station side）DPCCH method of reseptance comprises the following steps：Step 1, the base station belonging to second community obtains the 2nd TPC information from UE, wherein the second TPC information is used for the downlink power control for indicating the base station belonging to the second community.
For example, specified moment of the base station belonging to second community on each time slot receives the 2nd TPC information from UE side joints；Then, the base station belonging to second community decodes the 2nd TPC information, to obtain the 2nd TPC information.
Or, for example, the base station belonging to second community receives combined coding on each time slot from UE The first TPC information and the 2nd TPC information, wherein the first TPC information is used for the downlink power control for indicating base station belonging to first community；Then, the base station belonging to second community decodes the first TPC information and the 2nd TPC information of the combined coding, to obtain the 2nd TPC information in designated bit position.
Or, for example, the 2nd TPC information is received in base station belonging to second community on assigned timeslot from UE side joints respectively, wherein the first TPC information is transmitted from the 2nd TPC information on different time slots, the first TPC information is used for the downlink power control for indicating the base station belonging to first community；Then, the base station belonging to second community decodes the 2nd TPC information, to obtain the 2nd TPC information.
Step 52, the base station belonging to second community carries out downlink power control according to the 2nd TPC information.More than, it can be set in advance to specify moment, designated bit position and assigned timeslot.
As can be seen here, due to two TPC information of generation, and the two TPC information indicate respectively the descending probability control of the base station belonging to two different districts, therefore can ensure the down control channel quality of two different districts.
As shown in fig. 6, in dual-carrier double cell（DF-DC, Dual Frequency-Dual Carrier) the problem of not covered and covered by the second frequency F2 by micro-base station Pico the first frequency F1 for some cell occurs in scene.Assuming that Fig. 6 is the DF-DC scenes under Hetnet and MF collective effects, the situation that Pico fl frequencies are not covered but covered by f2 occurs in such a scenario.Therefore, in order to expand Pico coverage, it may be considered that down control channel is sent on Pico f2, the interference of such control channel can be reduced and covering problem can be also resolved.But, so have to construct alien frequencies soft handover, therefore occur that the down control channel for the cell 2 that the cell 1 and Pico of macro base station Macro coverings is covered will have very big difference.
Therefore, for this scene occurred in Fig. 6, the transmission method of the DPCCH such as the embodiment of the present invention can be used.Due to two descending TPC information of generation, and the two TPC information indicate respectively the base station belonging to two different districts（For example, the first TPC information is sent to Macro, the 2nd TPC information is sent to Pico) downlink power control, it is meant that Macro and Pico two downlinks carry out independent power control operation.It may therefore be assured that when two downlink qualities are widely different, the downlink power control of both links.
Fig. 7 shows a kind of DPCCH transmitting device.Wherein, DPCCH transmitting device 70 includes the first generation unit 71 and the first transmitting element 72.
For example, first generation unit 71 is used to generate the first TPC information and the 2nd TPC information, wherein described first TPC information is used for the downlink power control for indicating the base station belonging to first community, and the 2nd TPC information is used for the downlink power control for indicating the base station belonging to second community.First transmitting element 72 base stations for being used for respectively belonging to the base station belonging to the first community and the second community send the first TPC information and the 2nd TPC information.
In one embodiment, the first TPC information and the 2nd TPC information are by the DPCCH channel bearings, wherein described first TPC information and the 2nd TPC information are coded independently, or the first TPC information and the 2nd TPC information are jointly encoded.
Therefore, the first transmitting element 72 specifically for：When the first TPC information and the 2nd TPC information are coded independently, on identical time slot, the base station belonging to the first community sends the first TPC information, and base station transmission the 2nd TPC information belonging to the second community respectively；Or when the first TPC information and the 2nd TPC information are jointly encoded, on identical time slot, while the base station belonging to the base station belonging to the first community and the second community sends the first TPC information and the 2nd TPC information of combined coding.
In another embodiment, the first TPC information and the 2nd TPC information are transmitted in a time division manner, wherein the first TPC information and the 2nd TPC information by when Coded.
Therefore, the first transmitting element 72 specifically for：When the first TPC information and the 2nd TPC information by when Coded when, on interval slots in a time division manner, the base station belonging to the first community sends the first TPC information, and base station transmission the 2nd TPC information belonging to the second community respectively.
As can be seen here, due to two TPC information of generation, and the two TPC information indicate respectively the descending probability control of the base station belonging to two cells, therefore can independently ensure the down control channel quality of two cells.
It is appreciated that the transmitting device of the DPCCH can be only fitted in UE.
Fig. 8 shows a kind of DPCCH reception device.Wherein, DPCCH reception device 80 includes the control unit 82 of first acquisition unit 81 and first.
For example, first acquisition unit 81 is used to obtain the first TPC information from UE, wherein the first TPC information is used for the downlink power control for indicating the base station belonging to first community.First control unit 82 is used to carry out downlink power control according to the first TPC information.
